Detailed Description

The invention will be further described with reference to the accompanying figures 1-4 and examples.

Example 1: a closed liquid dung conveying system comprises a filtering pool 4 and a liquid level control mechanism arranged in the filtering pool 4, wherein the filtering pool 4 is divided into an A area 10, a B area 11 and a C area 12, the depth of a pool body of the filtering pool is determined by the buried depth of a water inlet pipeline at the front end, the filtering mechanism is arranged in the filtering pool, a water pump 3 of the liquid level control mechanism conveys liquid in the filtering pool 4 to a solid-liquid separator 8, and the solid-liquid separator 8 is connected with a PE storage tank 9 through a pipeline; PE storage tank 9 indicates that the liquid dung of carrying the environmental protection district no longer gets into big catch basin, adopts PE material jar to replace big catch basin, and is with low costs, sealed corrosion-resistant, long service life, and convenient operation, draws water and intake through liquid level controller is automatic.

The difference between example 2 and example 1 is: the liquid level control mechanism comprises an upper liquid level probe 13 and a lower liquid level probe 5 which are arranged in the filter tank, the upper liquid level probe 13 and the lower liquid level probe 5 are both connected with a liquid level controller, and the setting height of the liquid level control mechanism is determined according to the flow rate of the water pump and the water amount coming from the front end; the liquid level controller is connected with the filtering mechanism and the water pump; when the water level rises to a high water level, the water pump is contacted with the upper probe, and the water pump is automatically started to deliver water to the rear end through signal conversion, and stops delivering water when the water level falls to a low water level. The liquid level controller controls the liquid level height in the filter tank, so that the automatic start and stop of the water pump and the mechanical grating machine are realized, and the overflow of the over-high water level and the damage of the over-low idle running are avoided; the operation improves the water delivery efficiency, reduces the workload of personnel, and is more energy-saving and efficient.

The difference between example 3 and example 2 is: the filtering mechanism adopts a mechanical grating machine 1; the grid machine opens and stops and filter tank liquid level height linkage, when the water level rose to setting for the height, the grid began work, and the bold debris of clearance play excrement water when the water level reached low water level, grid, water pump stop work, and the solid debris of clearance are unified to be collected and are transported, and liquid in the debris flows back in the pond through the guide slot.

The difference between example 4 and example 3 is: be equipped with barricade 2 in the filtering ponds, clearance and filtering mechanism's width phase-match between 2 and the filtering ponds pond walls of barricade, mechanical grid machine installs on one of them side of filtering ponds, and the grid interval is selected according to liquid dung concentration and debris type, and grid machine end sets up rubbish collection bag or other collection mechanisms, transports to the refuse treatment point in unison at every interval, and grid machine need not people to operate and stops, but in the operation process, need regularly to patrol and strengthen the management, avoids blockking up or twine debris.

The difference between example 5 and example 4 is: a cover plate matched with the filter tank is arranged on the filter tank to ensure that the liquid dung is completely sealed; the filtering basin is used for receiving the liquid dung discharged by the pigsty, and the water pump is automatically started and stopped by monitoring the liquid level, so as to convey water to the rear end, and meanwhile, the filtering basin is used for placing a mechanical grating machine and filtering sundries in the liquid dung. The top of the filter tank is covered with a cover plate to ensure that the odor is not diffused.

The difference between example 6 and example 5 is: the tail end of the mechanical grating machine is provided with a garbage collecting mechanism.
